1637 results about "Carboxylate" patented technology

A carboxylate is the conjugate base of a carboxylic acid. Carboxylate salts have the general formula M(RCOO)ₙ, where M is a metal and n is 1, 2,...; carboxylate esters have the general formula RCOOR′ (or RCO₂R′). R and R′ are organic groups; R′ ≠ H.

Dimerized alcohol compositions and biodegradible surfactants made therefrom having cold water detergency

There is provided an alcohol composition obtained by dimerizing an olefin feed comprising C6-C10 linear olefins to obtain C12-C20 olefins, followed by conversion to alcohols, such as by hydroformylation. The composition has an average number of branches ranging from 0.9 to 2.0 per molecule. The linear olefin feed preferably comprises at least 85% of C6-C8-olefins. The primary alcohol compositions are then converted to anionic or nonionic surfactants, preferably sulfated or oxyalkylated or both. The sulfated compositions are biodegradable and possess good cold water detergency. The process for making the dimerized primary alcohol comprises dimerizing, in the presence of a homogeneous dimerization catalyst under dimerization conditions, an olefin feed comprising C6-C10 olefins and preferably at least 85 weight % of linear olefins based on the weight of the olefin feed, to obtain a C12-C20; optionally double bond isomerizing said C12-C20 olefins; and converting the C12-C20 olefins to alcohols, preferably through hydroformylation. The process is preferably a one-step dimerization. The homogenous catalyst comprises a mixture of a nickel carboxylate or a nickel chelate, with an alkyl aluminum halide or an alkyl aluminum alkoxide.

Method of bonding a window to a substrate using a silane functional adhesive composition

The invention is an adhesive composition comprising
    • a) i) a trialkoxysilane functional polyether or polyurethane wherein the polyether or polyurethane has a weight average molecular weight of 6000 or greater and a dialkyltin carboxylate or dialkyltin alcoholate; or
      • ii) a dialkoxysilane functional polyether or polyurethane and a dialkyltin alcoholate; and
    • b) a primary or secondary amino straight chain alkyl trialkoxysilane;
    • wherein the dialkyltin carboxylate or dialkyltin alcoholate is present in an effective amount to facilitate bonding of the adhesive to a substrate of from about 0.1 to about 1.0 percent by weight based on the weight of the adhesive and the primary or secondary amino straight chained alkyl trialkoxysilane is present in an amount which is effective to facilitate bonding of the adhesive to a substrate wherein the amount is from about 0.5 to about 1.2 percent by weight. In another embodiment, the invention is a method of bonding a window in a vehicle. The process comprises applying to a window or a window frame of a structure an adhesive according to the invention; contacting the window with the window frame of a substrate wherein the adhesive is located between the window and the substrate; and allowing the adhesive to cure. This process is especially useful when the substrate is unprimed metal, plastic, fiberglass or a composite, optionally coated with a coating. In another embodiment it is useful when the window is unprimed.

Ionizing radiation stable thermoplastic composition, method of making, and articles formed therefrom

A thermoplastic composition comprises a polycarbonate that is not aryl carboxylate end-capped, and an aryl carboxylate end-capped polycarbonate of formula:
wherein each Ar1 is independently an aryl group, -(-L-)m- is a polycarbonate linking group with m units of linking unit L, and m is at least one; wherein the aryl carboxylate end-capped polycarbonate has aryl carboxylate end groups present in the thermoplastic composition in an amount of 0.01 to 500 mmol/Kg based on the combined weights of the polycarbonate that is not aryl carboxylate end-capped, and the aryl carboxylate end-capped polycarbonate, and wherein a molded article having a thickness of 3.2±0.12 millimeters and consisting of the aryl carboxylate end-capped polycarbonate, the polycarbonate, and less than or equal to 1.0 percent total weight of aliphatic diol, a mold-release agent, and an antioxidant has, after exposure to a total gamma radiation dose of 81 kGy and when measured according to ASTM D1925-70, an increase in yellowness index (dYI) of less than or equal to 24.5, when compared to the unexposed molded article. A method for preparing the aryl carboxylate end-capped polycarbonate that is not aryl carboxylate end-capped, and thermoplastic composition, an article prepared from the thermoplastic composition, are also disclosed.
